Modules?

I've tried installing Arch multiple times but I always have some sort of showstopping issue, even post-installation. Previously I couldn't set up X because the configuration utility couldn't find a certain module file. I've been told that running the "depmod" command will generate this file but my question is, is there any manual configuration of kernel modules I have to do during installation? I'm not so comfortable with this aspect of setup and I'm not familiar with Linux designations for my hardware, so I used the "hwdetect" tool. Upon reaching the "Configure system" step of installation, I've noted that the kernel module file (the name escapes me at the moment) is empty, and that I would have to manually add entries. It seems like something may be missing, although I wouldn't exactly know where to go from here.

Re: Modules?

Basic system should work okay with only MOD_AUTOLOAD. Some modules you have to provide yourself when you want to enable some specific functionality, like speedstep/powernow or truecrypt. nvidia driver gets autoloaded by xorg if it's specified in xorg.conf.
